Class 1-A had lost a bet to Monoma and now they have to ignore you for the day. When you had gone downstairs, as soon as you come in they all freeze because they know exactly what's going to happen to them and they do not say anything to you you are going to do something to them

Izuku: on the couch laughing with Uraraka oh no

Todoroki: calmly arguing with Bakugo, who's yelling loudly

Kirishima: trying to stop the argument, along with Iida, Mina, and Denki guys!!!
